SUPPORT FOR SPINNING-SPINDLES.

SPECIFICATION forming part of Letters Patent N o. 408,185, dated July 30, 1889. Application filed January 22, 1889. Serial No. 297,143- (No model.)

To @ZZ whom, t may concern.-

Be it known that I, THOMAS Il. LOGAN, of Lowell, county of Middlesex, State of Massachusetts, have invented an Improvement in Supports for Spinning-Spindles, of which the following description, in connection with the accompanying drawings, is a speciiication, like letters on the drawings representing like parts.

This invention is intended as an improvement on that class of spindles known as selfcentering, and has for its object to simplify the construction of the parts and provide a bearing in which there shall be elasticity between the bolster and step.

In accordance with my invention a metallic bolster having' elastic or yielding` portions at one end is placed in a tube mounted loosely upon or in a holder, the said tube being free to yield vertically and also laterally, one or both, the said tube being' of suitable diameter externally to nearly ill the sleeve-whirl of the spindle, the bolster and loosely-mounted tube being the only parts interposed between the spindle and whirl.

My invention consists, essentially, in a yielding or elastic bolster and a tube in which it is held, and a holder to support the said tube loosely, combined with a sleeve-whirl spindle, the exterior of the said tube coming next the interior of the said sleeve-whirl, substantially as will be described; also, the combination, with aspindle, of an elastic bolster, a tube intei-posed between the said bolster and whirl, and a holder to receive the said tube, the said holder having' a detachable cap, which engages the lower end of the tube to keep it down in the holder, substantially as will be described.

Other features of my invention will be hereinafter pointed out in the claims at the end of this specification.

Figure l in section and elevation shows a spindle-support and spindle embodying my invention. Fig. 2 is a section below the line x of Fig. l, and Fig. 3 a modification.

The spindle a has a sleeve-whirl e. The

rail b receives the shank ofthe holder h", herein shown as provided with a cap b3, the shank of the holder being held in place by a nut b2. The cap b3 of the holder is screwed upon the upper threaded end (see Fig. l) of the portion b of the holder. Fig. l) as bored to receive the spiral spring CZ, and as chambered or recessed to receiveJ loosely the enlarged foot end c of the tube e', which is extended up into the sleeve-whirl, nearly filling the bore thereof. The tube c is kept down in the recess at the upper end of the holder by the cap h3, having the inturned edges to co-operate with the flaring lower end of the tube and keep it from being lifted out of place. The lower end of the tube and the chamber or recess in' the holder are of such diameter as to permit the tube to move somewhat laterally when required by the spindle.

weight ot' the tube and spindle rests, supports the said tube and spindle, so that they are permitted to yield vertically to a limited extent. The tube e receives within it a metal lic bolster f, which, as represented, is threaded and screwed into the tube e at its upper end, the said bolster being split longitudinally to form yielding arms f2, which come in contact with the spindle. This construction of bolster enables the lower end thereof located in the tube to yield or move laterally with the spindle in the said tube e', and at the same time the action of the spindle against the upper end of the bolster held in the said tube rigidly causes the tube to move at its foot or lower end with the spindle.

In Fig. l the end of the spindle is shown as iiattened to rest on a flat step; but in Fig. 3 the spindle end is tapered to enter a hole in the step part.

I have shown a washer g, preferably of ilexible material, as interposed between the spring and tube.

The rotation of the cap h3 may be made to compress the spring d, so as to afford greater or less vertical motion of the tube.

A pin or projection e4 prevents the tube e from rotating with the spindle.

The spindle may be oiled in any usual manner. Y

I do not claim a bolster held at one and The holder is shown (see The spring d, on which the slitted at but one side, as such a bolster is l not flexible, and does not contain yielding arms; nor do I herein claim a bolster composed of an unslotted tube in which the bolster enters, said bolster having yielding arms be- IOO tween its outer side and the interior of the supporting-case.

I claiml. The yielding or elastic bolster, the tube in which it is held, and a holder to support the said tube loosely, combined With a sleevewhirl spindle, the exterior of the said tube coming next the interior of the said sleevewhirl, substantially as described.

2. The spindle, the elastic bolster, and the tube interposed between the said bolster and Whirl, and a holder to receive t-he said tube, the said holder having a detachable cap, Which engages the lower end of the tube to keep it down in the holder, substantially as described.

3. The spindle, the elastic bolster, the tube in which it is held, the holder in which the said tube is mounted loosely, and the spring to support the Weight of the said tube and permit it to yield vertically, substantially as described.

4. The described bolster and step, consisting of a short tube e', closed at its bottom to hold oil, and a tubular or sleeve-like bolster open at both ends and having a series of independently-yielding flexible arms, a rigid portion of the said bolster coming in contact with the interior of the said tube, Whilethe said flexible arms bear directly against the spindle at opposite sides and yield independently to the requirements of the foot of the spindle as the latter moves, due to an unbalanced load.

5. The described bolster and step, consisting of a tube c and the bolster secured in the upper end of the step-t-ube and having iexible arms f2 extended Within the said tube, combined with a spindle and a holder for the said tube, and with a pin or projection to prevent the rotation of the tube with the spindle, substantially as described.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.

THOMAS H. LOGAN.
